Another TPI failure, installing the @TwoStrokePerformance injector relocation kit or at least trying to!

FINALLY!!!!! Lol
Watch out for lee andras Gator!
Lot of labor in those tires
That piston looks like lack of lubrication.
Merch hats are going to be restocked?
That is a bummer, was looking forward to this video since I have been looking at doing the whole two stroke performance mod to my 2018 250xc-w tpi. Are you doing the delete kit also or just leaving it oil injected with the kit? Curious for CO elevation why not the high comp insert? I was thinking med head for my 250 to get the most out of Low and maybe pull a higher gear since I can not really find a 300 kit for the 18 model 250 tpi.
I let my TPI idle and warm up while I put on my gear. Idle until good and warm.
Excellent point about TPI warmup. I've been saying it forever. 👍
What's the English translation for 'shlog'?
That's a nice pair of moose balls you got there 😂
You doing the oil pump delete with the split kit?
I wonder if the dealerships are warming up correctly even before delivery, or informing new owners about the warm up process.
tubes in winter are fine the rubber/foam gets so hard a moose is like 15-20lbs in a tire.
What kind of performance hit do you take when you install a cast iron sleeve instead of re-plating it with Nikasil? P.S. Don't Google "Moose Balls" HAHAHAHAHAHA!
TPI is a stupid idea. No lube on every start up is never good for any 2 stroke.
I relocated an injector & comverted to premix. Now it gets lube oil all the time.
A follow up on the installation of the TSP kit would be great. I have a buddy that has a 21 GGEX300 and I have a 22. I have ridden his and its nice. Mine takes a bit to warm up. I do the warm up thing while getting ready. We took off and my was still a little boggy, but his was nice and crisp. Seat of the pants his felt a bit stronger. I have thought about this kit.
So now that TBI pre-mix motors are out, the TPIs will scratch the cylinder if you don’t treat it like it’s delicate upon start up. They’ve been out how many years and how many times been started and revved a bit. If this is the case, they all have scratches?!!
"some balls are made for bouncing, some replace tubliss"
I have a 2020 300XCW and never purposely warmed it up differently. However, I put the GETECU race Kit on soon after I got it. It burned more gas after install, which the kit was suppose to cure the lean condition. The kit and Slaven's head really transformed the bike for the better.
Good video as always. 🤘
Over here in Scandinavia its like religion getting the tires studded perfect haha
Right feel in the rocks, right angle on the studs, right pattern on the rear for drive etc…
Funny part is some of the best tires for studs are reeally old treads that no sane person have used for summer in a very long time.
Could some explain how not warming up the TPI can cause to damage of the cylinder wall?
Thanks!
Man, i dont know. My tpi starts smoking pretty quick on cold startup. Within 30 seconds you have to think all the oil has coated. Now pinning it on start up..sure. But hard to believe 20-30 seconds of idle wouldnt oil cylinder.
Every 2 stroke I’ve ever had has had it’s own weird niche when it comes to starting. But I learned that if you can, just let it idle it’s way to temp. I cold locked a snowmobile up because the wiseco forged pistons take way longer to warm up than oem 😅. Also, we could always use some extra balls while riding.
Carb'd 2 strokes seen pistons with wear almost looks like cold seizures, like piston is all scored up lookin. Why people rev them to the moon when they are Cold makes no sense to me.
More likely the piston issue is from left over casting sand in related parts not getting fully cleaned out. I seen this issue from Volvo in their D13 engine years back. There was a nook where a small amount would be left.
Holy Crap those Mouse Ballz are bank $ 189 per wheel. Might as well call them ben wa balls, i'll stick with the nitros thanks
🤘
🤘
What's the benefits of the tsp relocation kit?
I've been running the tsp kit (hi comp) on my 2020 300xcw since about the 15 hour mark. Bike has been flawless for me.
My new bike locked up Sunday with 44hrs on it dropped it off at the dealer yesterday morning they called me today the piston skirt broke off a piece I heard it so killed it but not fast enough I guess wiped out a ton of shit pretty devastated myself
👍👍
🤘🤘 man that was in good information you gave on cold Seize I learned something new today thank you very much Morgan
Wait this bike had 50 miles on it?
I installed tsp's irk last week, already had their medium comp head. Got to ride it Sunday bike runs good
I always wondered what people do when racing ISDE rules with a TPI. You start with a cold bike after impound. Maybe pull over and let it warm up? Go slow for a while? You can’t wait too long or you could be late.
Any thoughts on running fuel through the throttle body with the relocation kit? I’ve had my questions whether or not it’s designed for it and could damage it?
Harvesting moose balls sounds terribly dangerous!
Morgan, your explanation of how TPI warm up is important and how a lot of people don't understand that issue, was perfect and spot on! Thank you. Most, like 99% of all TPI issues are caused from owner error during warm up. Others are caused by not filling the oil tank, getting dirt in the oil tank, etc. Other than owner errors they are extremely durable and dependable machines. You have to make sure and idle, warm up and take it seriously easy on TPI's for the first 6-8 minutes at least. Don't rev it up and try to "clean it out" you don't need to do that, either. After warming it up correctly, BRAAAAP! all day long!!!!!
Sounds like carburetors are still king 🤘
Straight talk here from someone who has logged hundreds of hours on several TPI bikes bought new. TPI was not properly tested and engineered for cold weather operation. When cold the injected oil coagulates on the reed block preventing proper oiling. All our multiple seizures were on the cold intake side of the piston. In addition the cooling system doesn’t keep the engine warm enough at light load/ low speed single track use. Poor oiling + insufficient expansion of piston and cylinder equals big problems. The pre mix bikes had none of these problems. That is why KTM is abandoning TPI after 15 years of development and 5 years of serial production. Thousands of owners beside myself have paid top dollar for unreliable and failure prone machines and received no help from the factory. These failures are very expensive to fix: figure $2500 on up at a shop depending on how many components are damaged. Extended warmup can mitigate cold seizure, but won’t eliminate it. I have been riding for 60 years and know how to treat a cold engine. Victim blaming the owner for poor engineering and development
is really poor form. You will sing a different tune when it happens to you. After 4 new KTM/ Husqvarna 300’s I have moved to the 4 stroke platforms. The 500 piston will go 1000 hours in recreational service with care. KTMs’ return to premix with TBI is all you need to know. They have lost me as a 2T customer.
🤘
I went from a 16 250 xcw to a 19 250 xcf. Until KTM gets the 2 strokes figured out or Yamaha gets off the butts and puts a button their 2T's, I'll be riding a 4 stroke.
😂Yamaha
Mindlessly pinging a bike so it "doesnt clog" is silly on a carb bike as well. A properly jetted carby starts and runs cold just fine. Any cold bike needs a slightly higher idle to run properly. What a lot of people miss is that cold bikes actually get way more film deposited due to condensation onto cold metal(the whole reason why your cold bike runs poorly in the first place).
KTM has a warm up procedure that works, but any of these bikes you can just ride slowly even when cold- that warms up – I almost never warm up my bikes at idle – hate the noise , but I also never rev them – have had 0 issues on high (200h+ bikes).
I do think that if you dont mod your TPI with and adjustable throttle stop they can be hard to start and run poorly when cold (also are lean at idle) – so that can cause people to rev them needlessly.
I have seen many stock TPI bikes that start poorly when cold – so maybe we can still blame the bike? lol
I dont know why people fret about these tiny cylinder scorns on 2 strokes – losing those 4psi makes a difference in their lap times? That piston looks hella weird tho
ya' think the oiling system on those bikes is why they don't have it anymore ?? …. just sayin' ….
